I added a black and white TIFF that I want to use to create a basemap to a project in ArcGIS Pro. When I look at the layer, it turned a light blue color.

Why is this so and how do I make it grayscale?

Rasters are just a grid of numbers - they don't inherently have colors attached to them. It sounds like the symbology of your raster defaulted to something different from what you were expecting. Trying selecting a different colormap or band combination under the Appearance tab for your raster layer.
